Precision isn't the issue. Story pointing isn't supposed to be 100% accurate either. It's supposed to shine a light on an otherwise opaque process. It works at that. This is the same.

I could quite easily spend all of my time refactoring and none on features and vice versa. There is no "right" amount as you seem to think, just a whole bunch of trade offs.

I think you underestimate the power of making something measurable and exposing it to upper management. That often changes behaviour in a quite radical way, especially among weasels.

And, you've never known development to be managed in this way because it's a new idea.
